Abstract

Shear reinforcement for retrofitting a reinforced concrete (RC) beam using unidirectional Carbon Fiber Reinforced Polymer (CFRP) woven can only be applied on the beam web below the concrete floor slab. Thus, it cannot fully confine like the way stirrups do, in which it will affect the shear capacity. The CFRP can only be ‘n’or ‘u’ shaped, taking into consideration the direction of shear force. Herein, the experimental study of the shear capacity of shear capacity the beam strengthened by FRP is carried out.shear capacity. The beams are RC beams of width 150 mm, height 300 mm, span of 1000 mm, f'c = 26 MPa having 2 bar of 19 mm diameter (fy = 403.65 MPa) and stirrups 6 mm diameter of 250 mm spacing (fy=375 MPa). The shear capacity measured is then compared with the shear capacity calculated using ACI 440. The result shows that the shear capacity measured from experiment is greater than the shear capacity calculated by ACI 440. Also, the shear capacity of RC beam with CFRP reinforcement n shape is greater than u shape.
